Title: | Large Solutions of Elliptic Equations with a Weakly Superlinear Nonlinearity | Contributor(s): | Cirstea, Florica Corina (author); Du, Yihong (author) | Publication Date: | 2007 | DOI: | 10.1007/s11854-008-0008-6 | Handle Link: | https://hdl.handle.net/1959.11/3545 | Abstract: | This paper studies the asymptotic behavior near the boundary for large solutions of the semilinear equation Δu + au = b(x)f(u) in a smooth bounded domain Ω of ℝN with N ≥ 2, where a is a real parameter and b is a nonnegative smooth function on... We assume that f(u) behaves like u(In u)α as u → ∞, for some α > 2. It turns out that this case is more difficult to handle than those where f(u) grows like u p (p > 1) or faster at infinity. Under suitable conditions on the weight function b(x), which may vanish on ∂Ω, we obtain the first order expansion of the large solutions near the boundary. We also obtain some uniqueness results. | Publication Type: | Journal Article | Source of Publication: | Journal d'Analyse Mathematique, 103(1), p. 261-277 | Publisher: | Magnes Press | Place of Publication: | Israel | ISSN: | 1565-8538 0021-7670 |
